Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100658, here are decompositions:
- 37 + 100621 = 100658
- 67 + 100591 = 100658
- 109 + 100549 = 100658
- 139 + 100519 = 100658
- 157 + 100501 = 100658
- 199 + 100459 = 100658
- 211 + 100447 = 100658
- 241 + 100417 = 100658
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 100,658 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
